Hi, today my horn stopped working. I have a 2008 Touareg 3.0 TDI. I checked the fuses which looked okay, although I am not sure I checked the right ones. Anyone got a fuse schematic for this model? I have also read it could be a problem with the horn itself, apparently taking off the front bumper and spraying some WD40 up the horn and waiting a day before laying on it again is a possible fix. Another possibility is the ground and connecting wires from the battery have come lose. Am I missing something here? My access to good tools to remove the front bumper is somewhat limited. I’m really hoping its just a fuse but I dont know which one.
